SHEET-IKE 7'0 uZZ whom it may concern:

lie it known that l, Ilicua an ll. Srnvrcns, olMnnhall, Alleghenycounty, ,lennsylvania, have invented a new and nset'ul Sheet-Metalliling, of which the l'ollowinc is a lull, clear, and exact de ption,relerence being hadto the iwcoinpanying drawings, forming part, of thisspecitication, in which Figure l is a plan viewiol' v sheet metal pilingcon structcd in accordance with li invention; Fig. 2 is a sideelevation; Fig. Cl is a. horizontal section on a larger sca'le showing;one ol' my improved interlocking members; Figs. "l and 5 showlllUtllllUtl corner constructions; l 'ig. ti shows a moditied term ofsheet metal piling, and Fig. 7 show anioditied torm ol the interlockingpiece.

My invention relates to the class of sheet metal pilings, especiallythat type wherein rolled commercial shapes are interlocked or connect edtogether to form the piling.

The object of my invention is to provide an interlocking shape which canbe used with flanged rolled shapes and will serve to connect themtogether to term the piling, without the use of rivets, bolts 01 othersocuring Illeans, except at corners or turns in the pilings.

in the drawings in which I show my invention as applied to commercialrolled shapes, 2, 2 repr sent a pair of channels which are connected bymy improved'in- 'lliis shape preterably consists of a terlocking shape.

web fl having base flanges l, "t and provided with upper inwardly bent;hooked flanges 5, 5. In other words the shape consists substantially ofan I-beain with upper flanges butt in to term hook flanges.

preferably roll the interlocking shape of such dimensions that theflanges (i of the channels 2 will be loosely engaged and held by theflanges of'the shape. Where the piling is used in mud. quiclesand, ordirt, the pilings may be used without packing, the shapes looselyengaging each other and being held by the hook flanges. Where the pilingis usedt'or shutting out Water, the joints between channels and theinterlocking shapes are prel'erably packed by suitable packing inaterial.7 which is l'orced in between the base flange of the lockingshape, and the web of the channel. In order to more securely hold suchpacking in position, I preferably bend the base flanges ot' theinterlocking shape inwardly to a. slight degree, so that the space between the channel and the base flange ot the shape will increaseslightly in depth toward the web of the shape. The packing will thus be.keyed or wedged in place. 'Ihe driving in otthis packing will thus makea water tight joint. The water being on the outside of the piling, itwater leaks into the space between the channel flanges and the web olthe interlocking shape, its pressure will act upon the packing and tendto wedge it tighter by l'orcing it into the wedge-shaped space.

Where the lace ol the piling changes direction I may rivet one baseflange 4 of the interlocking shape to the Specification of LettersPatent. Application tiled Janurti'y 11,1904. Serial No. 188,470-

flange 6 of the channel and then interlock the next channel flange G onthe other side of the shape, so that one line of rivets only isnecessary in changing direction in this manner. The corner may he aright angle, an obtuse angle or in the form of a gradual change ofdirection producing substantially a curve. In changing the angle of thepiling in the opposite direction I may adopt any one of severaldifferent connections; thus in Fig. 4, I show an angle 8 with its legriveted to the flange 6 with the interlocking shape on one side andtaking the place of the channel flange on this side. From this point on,the construction is the same as before. Instead of this angle connection1 may adopt that shown in,l*ig. 5, in which the flange 100i anotherchannel 11 is iveted to the web of the last channel, this extra chanrrainterlocking with the shape and the construction proceeding as bel'ore.

Instead of channels, I-bcains may he used as shown in Fig. (S of thedrawing, in which case the interlocking shape has both 01' its flangest, t bent so as to engage the flanges ot the l-heams.

In Fig. 7 I show a form similar to Figs. 1 to 5, but with the baseflanges t of the interlocking shape in their ordinary right angledposition.

The advantages of my invention result from the obtaining of maximumstrength for the piling with minimum weight metal. The structureconsisting simply oi rolled shapes, can be sold at low cost and puttogether without the use ol rivets or connections except at the cornersor turnings. Only two different shapes are used, namely the channel orother flanged shape, and the interlocking, shape. The system is adaptedto all kinds of pilings whether for shutting out water or otherwise, andthe packing will be securely held in place, an increase of waterpressure packing, it tighter.

The channels or Lbeains may he built up instead of rolled and many otherchanges may be made. in the form of the shapes t swell as in the formand size of the interlocking shape without departing from my invention.

I claim 1. Sheet metal piling comprising flanged shapes, an interlockingshape having flanges arranged to engage .the flanges of the other shapesand lock them together, and packing between the interlocking shape andthe other shapes; substantially as described.
